A plaque dedicated to Harald sits on the left side of archway that leads to the Palace of the Kings. It reads:
"Harald Reigned 1E 143 - 221"
He was the thirteenth of the line of Ysgramor, and is remembered as being the first King to relinquish all holdings in Atmora. Thus it was he that truly made the Nords a separate people, whose faces were turned firmly toward their destiny, the conquest of the vast new land of Tamriel.Indeed, the history of the Nords is the history of humans in Tamriel; all the human races, with the exception of the Redguards, are descended from Nordic stock, although in some the ancient blood admittedly runs thin.
Randagulf of the Begalin Clan, is recorded as being one of the mightiest warriors from Skyrim. He was known for his courage and ferocity in battle, and on many occasions, his participation was a major contributor to their victory. When Harald conquered Skyrim, Randagulf was defeated. So respectful of this great hero was Harald, that he took his gauntlets as his own. These gauntlets, worn by both mighty warriors, are believed to give the wearer additional strength.
According to the plaque in Winterhold and several other sources, the rule of King Harald is recorded as starting in 1E 143 and lasting for 78 years until his death in 1E 221, however the Pocket Guide to the Empire, First Edition: Skyrim mentions Skyrim was under his rule in 1E 113, which was also the year of his birth: "In the 113th year of the First Era, the entirety of modern Skyrim was under the reign of King Harald". This makes it unclear if Harald was crowned high king at birth in 1E 113 or if the pocket guide info is simply incorrect/retconned.
